hi all,

ive got an 2013 86 gts in aus w the digital speedo.

for a while i have thought the speedo is incorrect, so today i did a test with a gps speed tester.

EDITED (i had them around the wrong way)
when i do 100kmh on the speedo, the GPS shows 96kmh.
when i do 60kmh on the speedo, the GPS shows 56kmh.

seems its about 4kmh out.

the speed needle on the dash matches the digital dash readout speed.

anyone else noticed this with their car?

anyone know how to calibrate the speedo?

thanks, pop.
